I have seen the beer at Healthy Spirits on Castro and about 15th, and at Plumpjack in Noe Valley. Good Luck. I bought a bottle at Healthy Spirits in the summer, but managed to drink it already in November....

I have not had that specific brew, so am not sure if this would match, but I recently bought a Samuel Smith Cherry Ale at Whole Foods in Oakland, which (accorditing to the label) is a blend of two aged ales and cherry juice. They also make a version of this in raspberry, which I saw recently at Berkeley Bowl East. This fruit ale was distinct from the lambic-based fruit brews in that it lacks the lambic bitter-sour components. The fruit juice component is more distinct but is matched by the assertiveness of the aged ale. It is reminiscent of the Belgian product Fruli, although in that brew the fruit juice dominates the less assertive witbier component.
